If one side of the rectangle is a-2b, and the other side is 2A + B larger than the first side, the perimeter of the rectangle is a-2b______ .

If one side of the rectangle is a-2b, and the other side is 2A + B larger than the first side, the perimeter of the rectangle is a-2b______ .

The other side is 2A + B + a-2b = 3a-b. therefore, the perimeter of the rectangle is 2 [a-2b + 3a-b] = 8a-6b
